I have a 98 civic and i am about to get a 90 hatch.Can i take the whole wiring harness out of the 98 and put it in the hatch to make it obd2

 

It is possible, but why would you want to go through all that trouble to run OBD-II? Convert the 90's Existing harness to OBD-I, which is better.

 

well i have the 98 motor with dx bottom and vtec head and i want to put this in the hatch i am buying. The 98 is already torn apart so i was just going to see if i could use that plus i dont have that much money and i was going to try to use what i got

 

anyone else
